lw w I I I mn gawuawtoz lamina instead of being transmitted to the bolts 28, are taken by end flanges 19, thus relieving said bolts to a very great extent of the shearing strains. When unfastened, if the boxes are stuck, they may be readily released by' inserting a small pinch bar or other suitable tool in the sockets 24 so that they can be pried loose. The tie bars are also important features of the invention. Thus when a continuous bar' is employed, the intermediate portions thereof are secured against longitudinal movement by the lugs 32,- which relieve the bolt 33 of any shearing strain, and consequently the function of said bolt is merely to hold the tie bar in place or in interlock- In some cases, instead of a continuous tie bar as '27,"

a sectional tie bar may be advantageously used, and the side member is therefore provided with means whereby such sectional tie bar may be substituted for the continuous bar. To this end, the portions of the lower arch bar 13 directly on the outer sides of the columns 14 are provided with sockets or openings 39, shown more particularly in Fig. 10. Transverse openings 40 are located in the bar transversely of the sockets. The tie bar sections are inthe form of twisted straps or strips 41, their ends being located the' sockets 39,- and pivotally held in plade by bolts 42, their outer ends being disposed below the oil boxes 21 and secured thereto by the usual bolts 28. It will be evident that with the sectional bars, as shown in Fig. 10, practically the same results are secured as with the continuous bar, as'shown in Fig. 1.

In order to relieve the continuous tie bar holding bolt of strain, due to any displacement of the spring seat, the structure shown in Fig. 6 maybe employed. In this-embodiment, the lower bar of the frame is designated 13, and is provided with opposite outstanding ribs 14 that receive between theiri the spring seat 36. Said seat has in its under side asocket 35 that receives thehead 34 of the bolt' 33. This bolt secures in place the usual tie bar 27, and is located above the web 26- that connects the flanges. 25. Still another embodiment of this feature of the invention is'disclosed in Fig. 7. In this form of construction,

the lower frame member 13 is .provided with the usual depending flanges 25 connectedby a transverse web 26", and holding bolt 33? passing through the tie bar-27 has its upper end passing through a washer or holding plate 14 that is located in a socket 35 in the spring seat 36". p I

/ That the invention is not limitedto the particular style of truck disclosed in Figs. 1 and 10, will beevi dent by reference to Fig. 9, wherein the side member is of a slight conformation. In this embodiment, the side member may still be of cast steel, and comprises a frame 43 having a central bolster-receiving opening 44, the portion of the frame beneath said opening having the usual flanges 45, between which is secured the tie bar 46, by a bolt 47 in the manner already described. The ends of this frame are provided with ing ears 49 similar in construction to the ears 18.91 the structure already described. The-boxes 50, interposed between the extensions .47 and the ends of the tie bar 46, are held in place by the usual bolts 51. It will be evident that thisstructure so .far as the novel holding means for the boxes, is concerned, corresponds to that of the first described embodiment. 7 From the foregoing, it is thought-that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully-described. my invention, what I claimas new, and desire to secure by LettersPatent, is:

. 1. In a car truck, a side member having an extension, and inner and outer sets of ears carried by the extension and projecting on opposite sides of the some, said sets of ears being spaced apart to receive an oil box between them'and being provided in their under sides with recessed seats to receive the oil box ears.

In a car truck, a sidemember having an extension inner and outer sets of cars carried by the extension and projecting on opposite sides of the same, said ears being provided in their under sides with recessed oil box-re' 'ceiving seats, and inner and puterupright bolt-receiving openings formed in the extensions and opening centrally in the seats between the ears of the different sets. 1

3. In a car truck, a cast steel side member having extensions at its ends, each of the extensions having spaced sets of depending and oppositely extending ears provided with recessed seats in their under sides that receive the ears of the oil boxes, and said extensions being further more provided with upright bolt-receiving openings that open centrally in the seats.

4. In a car truck, a side member, having anoil box engaging seat, and a pinch bar receiving socket formed abovethe said seat.

5. In a car truck, a side member huvingan extension, ears carried by the extension and projecting on opposite sides of the same, said ears being provided in thelr'under sides with recessed 011 box receiving seats, and said extension being furthermore provided with a pinch bar receiving socket formed between the ears;

6. In a car truck, :1 cast steel side member having extensions at its ends, each ofthe extensions having spaced sets oi. depending and oppositely ,extending ears provided with recessed seats in their under sides that receive the ears of the oil boxes, said extensions being provided with upright boltreceiving openings communicatingwiththe seats, and with pinch bar receiving sockets formed between the ears.

T. In .a car truck, acast steel side member having ex tensions at its ends, spaced reinforcing ribs locatedpn the upper side of the'member and along the upper sides 01' the.

extension, spaced sets or depending and oppositely extending ears provided with recessed seats in their under sides that receive the ears of oil boxes, and upright boltreceiving openings formed in the extensions between the ribs and opening into the seats.
